changing emails...

I was able to change the forums with no issue.  I got on the console and to users and saw my original email and saw no way of changing it so I got the bright idea to create a new user other then the fact I enabled viewing passwords and didnt do that before I verified and got in.  I go to users and was going to delete the old account and cannot find that either.  How do I remove the account attached to the old email (or should I have done this another way) also once you enable password viewing can you not turn off that access?  
 
I dont know if I should have them delete the new one and change the old ones email since I had a tech support issue that is under the old email.

Thank you for your time
